SPECIFICATION forming part of Letters'Patent N0. 728,486, dated. May 19, 1903. Application filed December 14, 1901. Serial No. 85,963. (No model.)

110 a/ZZ whom t may con/cern:

Be it known that I, FRANCIS MEISEL, a citizen of the United States, Aresiding 'at Dover, in the county of Stratford and State of New Hampshire, have invented a new and useful Web-Roll Shaft, of which the following is a specication.

This invention relates to a web-roll shaft which has been especially designed for wind- Io ing or rewinding rolls of paper or similarfabrios. n The object of this invention is to provide a strong, simple, inexpensive, and efficient Collapsible web-roll shaft which canA be con- I5 tracted to permit the r same to be readily withdrawn from a wound-up completed webroll.

To these ends this invention consists of the web-roll shaft as an article of manufacture zo and of thecombinations of parts therein, as hereinafter described, and more particularly pointed out in the claims'at the end of this specification.l

In the accompanying drawings,Figure 1 is z 5 alongitudinal sectional view,partially broken v away, of a web-roll shaft constructed according to this invention. Fig. 2 is a fragmentary sectional view illustrating the relative position of the parts when the segmental shell of 3o the shaft is expanded. Fig. 3 is a similar view showing the relation of the parts when the shaft is contracted. Fig. 4 is a fragmentary perspective view of one of the segments which form the segmental shell. Fig. 5 is a transverse sectional view of the construction, and Fig. 6 is an end view of a webrollwound on a web-roll shaft constructed according to this invention. I In manufacturing certain grades of paper 4o webs are now frequently made from sixty to one hundredand fifty inches in width,'the

tendency of modern paper-mill equipment be? ing to increase the widths of paper manufactured. In a number of Operations incident to haudling wide webs of paper-such, for example, as in rewinding or slitting the webs-the Webroll shafts have to be inserted or removed from the web-rolls, and it frequently happens 5o that in driving or inserting ordinary solid web-roll shafts the web-rolls will be injured or driven out of true and the paper itself damaged.

The especial objectof this invention is to provide a simple, inexpensive, and efficient web- 5 5 rollshaft which can be inserted or removed from a web-roll without driving or forcing the same and which after being placed in position can be powerfully expanded to fit tightly into a web-roll hole. To'accomplish this result, a web-roll shaft constructed-according to'this p invention consists, essentially, of a segmental shell'and a longitudinally-movable adjusting-rod'for expanding the segmental shell. The number of pieces which may be employed v to form the segmental shell may be varied. Usually I have employed'four separate sections for this purpose. The segmental-shell sections are held in place by fingers or projections engaging annular grooves in collars 7o or rings carried by the adjusting-rod, and formed on said collars or rings or directly on the adj usting-rod are cam-sections which spread the'segmental-shell sections when the adjusting-rod is moved in one direction and which permit the segmental-shell sections to be contracted whenfthe adjusting-rod is loosened.

Referring to the accompanying drawings and in detail, 10 designates an'adjusting rod or shaft having the usual journals 11 at its ends. Threaded onto the adj usting-rod near .one end is a nut 12, which is held in place so `that it cannot be removed from the rod by means of stop-nuts 13. Inclosing the adjusting-rod 1 0 is a segmental shell comprising a number of sections A. In the present in'- stance the segmental shell consists of four sections. At one end the sections A are provided with collar-segments 14, which iit into 9o 'an annular groove in the nut 12, and pinned Tonto the nut 12 to incluse the projecting ends "of the collar-segments 14 is a ring 15.

Secured at aA number of points along the adjusting-rod 10 or formed integrally therewith 95 at such distances apart as may be deemed desirable are collars or rings 16, which col-- lars'or'rings 16 are provided with annular grooves 17 and spreading-cams 19. The

spreading-cams 19 engage bevel-faces of Ico ring sections 18, pinned or otherwise secured to the sections of the segmental shell A.

The ring-sections 18, as illustrated most clearly in Fig. 4, are provided with projections 20, engaging the annular groove 17 of the collar 16 to hold the parts of the segmental shell in place when the Web-roll'shaft is removed from a Web-roll.

The sections of the segmental shell, as herein illustrated, ale held from turning by means of pins 2l engaging slots in the sections of the segmental shell or in the fingers 2O projecting therefrom. By means of this construction I have provided a web-roll shaft the sections of which are expanded when the adjusting-rod 10 is moved in one direction, as illustrated in Fig. 2, and in which the segmental shell may be contracted when the adjusting-rod is moved in the opposite direction, as illustrated in Fig. 3.

I am aware that numerous changes may be made in the construction of my Web-roll shaft by those who are skilled in the art without departing from the scope of my invention as expressed in the claims.

The especial novelty of my construction resides in providing each of the sections A of the expansible shell with fingers or projections 20 of sufcient length to extend some distance into the annular grooves in the collars or rings of the adjusting-rod, so that provision will be made for snicient longitudinal motion between the parts to secure the desired adjustment without the necessity of unfastening screws or other fastening devices, the construction always being ready for adjustment by merely turning the adjusting-nut.

A further point of novelty in my construction consists in providing each of the sections A with a slot or keyway to engage a corresponding pin in one of the collars on the adjusting-rod so that the parts Will turn together.

I do not wish, therefore, to be limited to the construction I have herein shown and described; but v What I do claim, and desire to secure by Letters Patent of the United States, is-

1. As an article of manufacture, an expansible Web-roll shaft comprising a spindle or rod having collars or cam-sections thereon, an expansible shell comprising segmental sections, each one of which is provided at its ends with projections or fingers engaging annular grooves in the collars on the spindle, said fingers extending far enough into said grooves to permit the longitudinal adjustment of the parts required for expanding the shaft, and means for moving the spindle.

2. As an article of manufacture, an expansible web-roll shaft comprising a spindle 10, collars carried by said spindle, each of said collars having a cam-section and an annular retaining-groove, an expansible shell comprising segmental sections, each of which is provided at its ends with an extending finger which fits far enough into the annulargroove of one of said collars to permit the longitudinal motion of the parts required for adjustment, each of said fingers having a keyway 0r groove for engaging a pin or key in a collar to hold the parts from turning, and au adjusting-nut for shifting the central spindle to expand the shell or permit the same to con tract.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.

FRANCIS MEISEL.
